Welcome :) I am a PhD candidate in Quantitative Marketing at Johnson, Cornell University.
My research develops new statistical methods, drawing on econometrics, Bayesian statistics, and machine learning, to answer consumer-welfare questions that matter to managers, scholars, and policymakers. My current work builds methods for valid statistical inference when outcomes are measured with error, including measurements produced by large language models. Substantively, I study consumer welfare in housing markets, the largest expense most households carry, with a broader interest in consumers’ major financial decisions.
Before my doctoral studies, I spent five years as a quantitative researcher in Seoul, first at NICE Pricing and Information, where I built credit-risk and derivatives models, and later at December & Company Asset Management, where I designed machine-learning portfolio strategies. Working with data on credit, household consumption, and financial choices drew me toward the consumer-welfare questions that shape my work today.
Here is a list of things I believe in:
- “The greatest joy of research is recognizing, with clarity, what you don’t yet understand—and then, every so often, experiencing the rare moment when the unknown finally becomes clear.” - June Huh
- “Research is a long conversation—and important, original ideas emerge from the slow accumulation of that conversation.” - June Huh
- “The unknown thing to be known appeared to me as some stretch of earth or hard marl, resisting penetration… the sea advances insensibly in silence, nothing seems to happen, nothing moves, the water is so far off you hardly hear it… yet it finally surrounds the resistant substance.” - Alexander Grothendieck
- “…put the cutting edge of the chisel against the shell and strike hard. If needed, begin again at many different points until the shell cracks—and you are satisfied.” - Alexander Grothendieck
- “If the result confirms the hypothesis, then you’ve made a measurement. If the result is contrary to the hypothesis, then you’ve made a discovery.” - Enrico Fermi
- “‘Science progresses one funeral at a time.’ The future depends on some graduate student who is deeply suspicious of everything I have said.” - Geoff Hinton
- The Feynman Problem Solving Algorithm - Coined in jest by Nobel Prize-winning physicist, Murray Gell-Mann
- Write down the problem
- Think real hard
- Write down the solution
